5.17 SNMP Configuration
To enter the SNMP configuration it is possible with SNMP agent v1/v2 or v3 configuration which sends
information about the router, eventually about the I/O inputs.
SNMP (Simple Network Management Protocol) provides status information about network elements
such as routers or end computers. v1, v2 and v3 are just different versions of the SNMP. In the version
v3 the communication is secured (encrypted), except of the notification messages (such as notifications
of events – Traps). To enable using of SNMP service, check the Enable SNMP agent item.
Item Description
Name Designation of the router.
Location Placing of the router.
Contact Person who manages the router together with information how to con-
tact this person.
SNMP agent configuration
Enabling SNMPv1/v2 is performed using the Enable SNMPv1/v2 access item. It is also necessary to de-
fine a password for access to the SNMP agent ( Community ). Standard public is predefined.
Note!
At SNMPv1/v2 it is possible to define a different password for
Read
community (read only) and
Write
community (read and write). At SNMPv3 you can define two SNMP users. The first can
read only (
Read
), the second can read and write (
Write
). The items in the following table can be
set up for every user separately. These are not identical with the router’s Web interface users,
just the SNMP access users.
The
Enable SNMPv3 access
item allows you to enable SNMPv3. Then you must define the following pa-
rameters:
Item Description
Username User name
Authentication Encryption algorithm on the Authentication Protocol that is used to en-
sure the identity of users.
Authentication Password Password used to generate the key used for authentication.
Privacy Encryption algorithm on the Privacy Protocol that is used to ensure con-
fidentiality of data.
Privacy Password Password for encryption on the Privacy Protocol.
SNMPv3 configuration
By choosing
Enable I/O
extension it is possible to monitor binary inputs I/O on the router.
Enabling
Enable M-BUS
extension has no meaning at this time, since v3 routers doesn’t allow the instal-
lation of the M-BUS port yet.
